Early stage litter decomposition across biomes
(Elsevier, 2018-02-22)Through litter decomposition enormous amounts of carbon is emitted to the atmosphere. Numerous large-scale decomposition experiments have been conducted focusing on this fundamental soil process in order to understand the ... -
Variable retention forestry conserves habitat of bird species in Patagonian Nothofagus pumilio forests
("Marin Drăcea" National Research-Development Institute in Forestry, 2018-12-31)Variable retention is an alternative harvesting system that could be implemented instead the more traditional ones (e.g. shelterwood cut for N. pumilio forests in southern Patagonia), because it was designed not only for ... -
Reply to: Data do not support large-scale oligotrophication of terrestrial ecosystems.
(Springer Nature, 2019-07-22)Hiltbrunner et al. apply a reductionist approach to argue that the evidence for widespread terrestrial oligotrophication2 should be replaced with a two-factor explanation (growth dilution and depositional signatures) that ... -
Climatic controls of decomposition drive the global biogeography of forest tree symbioses
(Springer Nature, 2019-05-15)The identity of the dominant root-associated microbial symbionts in a forest determines the ability of trees to access limiting nutrients from atmospheric or soil pools1,2, sequester carbon3,4 and withstand the effects of ... -
TRY plant trait database – enhanced coverage and open access
(John Wiley & Sons Ltd., 2019-12-31)Plant traits—the morphological, anatomical, physiological, biochemical and phenological characteristics of plants—determine how plants respond to environmental factors, affect other trophic levels, and influence ecosystem ... -
Rangeland grazing management in Argentine Patagonia
(IJAB. Friends science publishers, 2020-08-31)Stocking rate adjustment in grazing management is recommended as a management tool to sustain productivity and improve soil health of permanent grassland ecosystems. The aim of this project was to assess the effect of ... -
Holistic versus continuous grazing in Patagonia: A station-scale case study of plant and animal production
(Elsevier, 2021-01)We compared animal and vegetation responses of a 13 600-ha area under holistic grazing management (HGM) with a similar area under continuous grazing (CGM) in a Patagonian station. Limitations were a dry 2012 −2016 experimental ... -
Changes in forest structure values along the natural cycle and different management strategies in Nothofagus antarctica forests
(Elsevier, 2021-04-15)Ecologically sustainable forest management aims to preserve ecosystem integrity by providing wood and non-wood values. For this, it is necessary to determine the losses produced by the different management practices in ... -
General destabilizing effects of eutrophication on grassland productivity at multiple spatial scales
(Springer Nature, 2020-10-23)Eutrophication is a widespread environmental change that usually reduces the stabilizing effect of plant diversity on productivity in local communities. Whether this effect is scale dependent remains to be elucidated. Here, ... -
Biophysical and socioeconomic factors influencing soil carbon stocks: a global assessment
(Springer, 2020-07-24)Soil is the most important terrestrial carbon (C) reservoir but is greatly impacted by land use change (LUC). Previous analyses of LUC impacts on soil C have focused on biophysical variables, leaving aside the influence ... -
La Agricultura familiar en Santa Cruz, Patagonia Argentina : caracterización de los núcleos agrícolas familiares
(Universidad Nacional de la Patagonia Austral (UNPA), 2020-11-13)La agricultura familiar abarca a un grupo grande de personas que tienen distintos orígenes y una amplia diversidad cultural, pero que mantienen en común la producción de alimentos como forma de vida. El objetivo del presente ... -
Carbon footprint of lamb and Wool production at farm gate and the regional sale in southern Patagonia
(MDPI, 2020-04-11)Natural steppe grasslands are the principal food resource for sheep in the Patagonia region, reared for meat and wool. However, there is currently a concern about the relationship between ruminant livestock and climate ... -
Biomasa y respiración microbiana : respuesta ante cambios en la humedad del suelo en la Estepa Magallánica Seca de Santa Cruz, Argentina
(Universidad Nacional de la Patagonia Austral (UNPA), 2020-11-17)El carbono y el nitrógeno de la biomasa microbiana (CBM y NBM) del suelo son bioindicadores que tienen el potencial de mostrar cambios en el suelo de los ecosistemas, y están condicionados por la humedad disponible en el ... -
Human footprint defining conservation strategies in Patagonian landscapes: Where we are and where we want to go?
(Elsevier, 2021-02)Understanding human influence on ecosystems and their services is crucial to achieve sustainable development and ensure the conservation of biodiversity. In this context, the human footprint index (HFI) represents the ... -
Recent deforestation drove the spike in Amazonian fires
(IOP Publishing, 2020-12-11)Tropical forests are of global importance even though they only cover around 10% of the Earth's land surface. They store large amounts of carbon and host between one-half and two-thirds of the world's species (Lewis 2006). ... -
Evaluación de indicadores de degradación y biomasa radical en mallines de una cuenca hídrica del sur de Santa Cruz
(Asociación Argentina de Ecología, 2020)Se planteó un estudio con el objetivo de analizar la asociación entre indicadores de deterioro del suelo y la vegetación, evaluar los cambios de esas variables entre sectores y condiciones de degradación, y monitorear ... -
Co-benefits of soil carbon protection for invertebrate conservation
(Elsevier, 2020-12)The global decline in invertebrate diversity requires urgent conservation interventions. However, identifying priority conservation areas for invertebrates remains a significant challenge. We hypothesized that aligning the ... -
Are Patagonia grasslands being overgrazed? A response to Marino et al. (2020)
(Wiley, 2020-09)Based upon primary productivity estimates, Oliva et al. (2019) concluded that, at the end of last century and after long periods of overgrazing, Patagonia's domestic stocks adjusted to regional‐scale herbivore carrying ... -
